the intertextual relationship of the story of the gonbade siah with the Koran based on lexical analysis

“Haft-Peykar” is one of the most prominent literary works with symbolic expressions that many of its linguistic capacities remain unknown. Since the content of a coalition work indicates the meanings of words and their applications, and also the lexical manifestation of style is rather more in the work than other layers, the analysis of the lexical layer is more effective in discovering the linguistic capacities and artistic connection of language and meaning. It is tried in this study to determine the role of this linguistic structure in creating and representing the secondary narrative by examining the lexical layer, especially the art of selecting words in the Black Dome. In order for the words to be effective and for the reader to understand the text more deeply, the poet narrates a story parallel to the story of the Black Dome at the lower level. The choice of terminology in “Nezami’s” words is appropriate with their value in the textual and hypertext context. Hence, the words that play a role in representing the deep narrative are symbolic codes that provide multiple understanding potentials in the content, and from a structural point of view, they are loops for constructing the continuity in the deep narrative that is constructed and associated with the events of the story in such a way that their omission destructs the perception of the secondary narrative. Paying attention to the frequency and homogeneity take the words out of monotony. On the other hand, presenting the story codes in a polysemous way, calligraphy, adjective substituting the noun, and bringing a personal pronoun before them, are suitable ways to highlight the codes.
